A flexible coupling for shafts, including opposed disks for attachment to the shafts, each'of said disks having a central shaft. receiving hub, a ring loosely mounted on each hub and adapted to bear against the outer face of the adjacent disk, flanges extending inwardly from the rings, and means connecting the rings for binding the flanges together to form a casing, said means extending loosely through the disks, said disks being normally spaced apart, said disks being tiltable and slidable relative to each other and to the rings.

4. A flexible coupling for shafts, including opposed disks for attachment to the v shafts, each of said disks haying a central shaft receiving hub, a ring loosely mounted on each hub and adapted to bear against the outer face of the adjacent disk, flanges extending inwardly from the rings and interfitting, and means connecting the rings for.

5. A flexible coupling for shafts, includ ing disks having shaft receiving hubs, a cas ing made up of opposed sections loosely mounted on the hubs and provided with interfitting annular flanges, said disks being normally spaced apart within the casing, and bolts extending transversely through the casing and disks for holding the parts of the casing together and for coupling the disks to the casing, said disks being mounted for relative sliding and tilting movement upon said ,bolts.
